Ok so I have 3 children 18,14 and 12. I split from their dad 2 years ago and they have very little contact with him (once every 4/5 months). I plan on booking a 4 day trip for just myself to Europe. My neighbour will be watching over them and my 18 year old will be home. My workmates will also be available to help them if needed. They will see me me on day 1 and 4 of the break due to flight times. Of course I will make sure they have food, stuff for emergencies etc. My ex is now telling me I’m selfish and wrong for taking this break. What do you guys think.
